One of the reasons I like doing PlayRaws is that it stress-tests rawproc. The filename here presented vexation; for some reason the umlat characters confound my filename parsing. I bullet-proofed some of my functions as a result, so the filename now results in “Unknown Image” rather than abject crash. Progress…
With a renamed copy of the .DNG, I proceeded with processing, here’s the resuit:
The processing:
- colorspace:ClayRGB-elle-V4-g22.icc,assign - Neither dcraw.c or camconst.json contained a specific Pentax K-50 set of primaries, so I messed around a bit with finding some. I got the Adobe DCP for the camera, but got tired of trying to figure out how to get a ForwardMatrix from the duai-illuminant matrices so I just went poking through @Elle’s profiles until I found one that gave a nice result when converted to sRGB. That happened to be ClayRGB, her Adobe1998 equivalent, with a 2.2 gamma TRC. So, gotta ask, what’d you do to the raw data converting to the DNG? Anyway…
- whitebalance:camera - As-shot, no further modification.
-
demosaic:lmmse - @heckflosse recommends this or IGV for noisy images. I usually defer to smart folk…
- blackwhitepoint:rgb,data - stretch the data to the container limit, 0.0 - 1.0.
- denoise:wavelet,0.032000 - I tried my NLmeans algorithm, but got tired of waiting for it to complete (need to optimize it, laziness…). A light touch of dcraw-derived wavelet.
- tone:filmic,6.20,0.02,1.50,0.90,1.00,norm - Been having fun figuring out the Duiker ABCD parameters of the original filmic curve. This image was low-DR, so the manipulations were a departure from my recent messing-around. The B-coeff (0.02) is similar though, I like the treatment of the toe it renders. The rest was just sliding stuff back and forth until I liked the result. Someday, this’ll have cogent heuristics, at least in my head…
- resize:1080 - PlayRaw resizing.
- sharpen:2 - More output sharpening than I usually do, no good explanation…
I liked this image a lot; IMHO its composition is really nice. Interesting processing challenge, makes me think more about rawproc2…
